HOW DID THIS MAGIC WORK?

it didn't

game flashed a white square on a black screen when you pulled the trigger. photosensor in gun looks to see if its pointed at white square. if yes: hit. if no: no hit

lol

the duck would turn into a white square for split second. The sensor would pick up on this if aimed at it.

Get good

Also, because of this, poorly written games would register a "hit" if you pulled the trigger aimed at a lightbulb.

Better written ones wouldn't. Also, better written ones would basically show one target per frame, and rotate through the targets. So your frame rate affected the number of targets, which is one of the reasons the games were so limited, and why they moved to other techniques.

That's still pretty fucking smart for howhat limited with technology they were (at least readily available, consumer grade tech). I can't believe they were able to come up with anything that worked at all

>>58521394
it was a lens, a photodiode, and a trigger.

pulling the trigger told the software to start the hit detection routine, which boiled down to making the target turn into a bright white square and then determining whether the lens/sensor was pointed at it.

because TVs were all CRTs with established timings (e.g., NTSC was 483 visible rows from 525 scanlines total per 59.94 Hz frame), the gun could look for periodic light signals and know which bright square if any was being aimed at.

nevermind, as per:

the algorithm is much simpler: just looking for a bright flash following a dark frame.

LCDs don't work not because of no beam scanning but because input lag fucks over the detection logic.

Huh, I'd say that the lag on some LCD's isn't that bad, but I guess on CRT's the response was literally instant. The console knew exactly which pixel it was drawing at any given time, wow.

That's because you have very limited imagination

fucking idiot, kill yourself, arrogant prick

you're the same kind of autist that claims "YEAH WELL AKCHUALLY I WOULD HAVE GOTTEN THAT WHOLE GRAVITY THING WITHOUT NEWTON"

what >>58521805 said is correct, that solution was pretty fucking smart

show me one fucking other VIABLE solution they could have used with their technology at that time

Given that light pens had been invented 30 years earlier I'd say you're pretty dumb if you "can't believe they were able to come up with anything that worked at all". The basic principle of the zapper is more primitive than a light pen.
